lhajZZ whom t may concern.'

it known that I, Ti-'inononnPnEsoorr ,Duivena 'citizen oftheUnitedStates, re-

siding at Melrose,l in the county of Middle- .sex and 4StateofMassachusetts, yhave invent- A,ed Inew' and' useful Improvements inAutomobile-Lamps, oiwhichthe following is a specication.

My invention relates to electric lamps for use in automobiles and forsimilar purposes.

The object of my invention is to provide a lamp to be operated by a drybattery, and one that is easily accessible tothe operator and iseconomical to construct.

In the accompanying drawing illustrating my invention, Figure 1 is aperspective view of my invention. Fig. 2 is a vertical section of Fig. 1through the line.' A-A. Fig. 8 is an edge view of the dash-board of anautomobile, having one of my lamps installed therein. Fig. 4 is a planview of the inside of the cap-of the receptacle. Fig. 5 is `-a plansviewof the inside .certain parts removed. 251` Similar numerals indicatecorresponding parts in all the figures 'of the drawing.

Referring to the drawing, 6 represents a receptacle made ofgutta-pereha, fiberor i other suitable material, cylindrical iii-form,-

and composed of the main portion [7 'fand' the cap 8.

9 is the lens of the receptacle, which is prevented from displacement bythe hemispherical shaped metallic reflector 1Q containing anincandescent lamp 11 operated by a dry battery, with which it isconnected by the conductors 12 and 13. The `cap 8 of the receptacle hasa circular recess 14C formed on the inside surface.

15 is a disk made of wood, liber or any other suitable insulatingmaterial, having a flshaped notch 16. cut therein.` The conductor 13 Yisconnected with a liat'spring 17 `which forms one pole of the battery,and

with which the switch 18 makes and breaks Contact. The conductor 12 isconnected with ,K a spring metallic uprightpiece 19, whichw forms theopposite pole of the battery. The switch 18 consists of a banjo shapedresilient piece of copper,"the body et' which lits loosely in thecircular recess 111 of the cap 8, when not in contact with the polepiece 1 7. The body of the switch 18 is conned in the recess 14: by thedisk 15, and the neck of the switch lies in a shallow recess 20 in thesurby the face of the cap 8 to a depth about equal to the thickness ofthe material of which the switch 18 is formed. The` switch rests on theedge 29 of the recesses 14 and 20, which thus serves asA a fulcrum.. Theneck of the switch is kinked at 26 thus bringing the body closer to thedisk 15. The pole piece 17 formed of resilient material is bent down-Wardly through the notch 16, and bears upon the surface of the cap 8 'inthe recess 20, forming a spring, so that when the switch 18 is forcedbeneath the pole piece 17, the pole piece holds the body of the switch18 against the underside of'the disk 15 with yielding pressure. The polepieces 1'? and '19 and the disk 15 are secured to the cap 8 screws 21,which-also serve to contine the conductors andlcibnnectthem.with thepole pieces 17 and 19.

When the parts are assembled, secured to the receptacle by bolts-22,extending through Jthe flange 23. rThe base 24 of the lamp will thenextend through the centhe cap is when' the latter is' forced under thepole piece 17. Theyielding pressure of theswitch 18 will alwaysinsureeontact of the switch with the base .24 when the switch is thusconfined by the pole piece 17. The upright pole piece 19irests incontact with the metallic reflector 10 with Va yielding pressure,thereby forming a circuit through the lamp. I construct the receptaclein the form of a cylindrical box 6 with the liange 23 for the purpose ofhaving the,lens of the receptacle protrude outside the dash-board, andhaving the flange 28 rest against the inside of the dashfboard 'andrendering ,the switch readily accessible to the operatorwithin the car.`

Two of'these lamps may be -installed'in the dash-board of the car andconnected -with a dry battery in series, and so installed that bothlamps may be lthrown into and out of circuit by the switch of eitherlamp.

l find that two lamps of the character described and installed inthedash-board will provide the necessary head lights, when the large headlights are out of order or fail for any reason, and that they willalways enable the'operator to extinguish the la'rge when the car isstanding in a head lights i Y public place, thereby saving the expenseincident to running the latter at such time. The construction of my lampis exceed- 'Patented oct. as, 1ers.'

tral opening l25 in the disk 1,5,and Contact 'with' thebody of theswitch 18 will result l l l l ters Patent is:

adapted to press on said switch andV estab ingly simple and economical,and the appli l cation of it to the dash-board of an antoniobile isconvenient and inexpensive. lt also furnishes" a 'suitable light at avery slight eX- pense. v,

It is obvious that. a lamp of the construe tion described is useful inmany places, such as 'for the purpose of lighting the interior orexterior of automobiles, and sailing lights for motor boats.

W hat I claim and desire to secure by Let- 1. In a receptacle containingan electric lamp, the combination .of a cap provided with a recess, aswitch loosely contained in said recess and adapted to bear against theedge of the recess as a fulcrum, and a spring lish Contact between saidswitch and the base of the lamp.

2. in a receptacle containing an electric lamp, the combination of a capprovided with a recess, a switch loosely iitting said recess', a disk ofinsulating material adapted to coniine said switch in saidlrecess, saiddisk having an opening adapted to permit contact between the base ot thelamp and the body of the 'switch` and aspring adapted to establish suchcontact.

3. in a receptacle containing an electric lamp, the combination of acylindrical main portion provided with an annular flange at one end, acap provided with a recess adapted to be secured thereto, a switchloosely con. tained in said recess, and a spring adapted to establishcontact between said switch and the base of the lamp, said main portionbeing adapted to extend through the dash board oil a vehicle, and theflange adapted to be located on the inside of the' dash board.

a. In an electric lamp holder, the combination of a cap of insulatingmaterial liaving a central circular recess on its inner face, and aradial V-shaped notch extending from said recess to the circumferenceofthe cap, a plate of insulating material adapted to be fastened to theinner tace of the cap and provided with an opening registerng'with therecess in the cap, a banjdshaped switch lying in said recess andV-shaped notch', and contact means carried on the exterior ot the platebut overhanging the edge thereof and adapted to rest on the extremity ofthe switch when the latter isin one position in the Vshaped notch, butclearing the switch when it is in other positions therein.

5. In an electric lamp holder the combina-V tion of a cap of insulatingniaterial having a central circular recess on itsinner face, and aradial \-shaped notch extending from said recess to the circumference ofthe cap, a plate of insulating material adapted to be fastened 'to theinner ace of the cap and provided with an opening registering with therecess in the cap, aoanjo-shaped switch lying in said recess and V-haped notch, and Contact means carried on the exterior of the plate butoverhanging the edge thereof and adapted to rest on the extremity of theswitch when in one position in the v -sha-ped notch, but .clearing thesame when in other positions therein, together with a metal re- Hector,provided with a central opening adapted to receive and make contact withthe side of a lamp base, means for holding said reflector in front ofthe plate with said opening concentric withthe plate opening, andelectric conductors connected one to the above mentioned contact means,and the other to the reflector.

6. In an electric lamp holder, the combination of a cap of insulatingmaterial having a central circular recess on its inner face, and aradial V-shaped notch extending from said recess to the.'circumferenceof the cap, a plate of insulating material adapted to be fastened to theinner face of the cap and provided with an opening registering with therecess in the cap, a switch lying in said h recess and `V-shaped notch,`means carried on the exterior of the plate and contact but overhangingthe edge thereof and adapted to rest en the extremity of the switch whenin one position in the V-shaped notch, but clearing the same when inother positions therein, together with means for holding an incandescentlamp in liront of said plate with its base pro]ecting through theopening Ytherein and in contact with the switch.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses, this 17 th day of October, 1912.
